Nakano Note (Nakano wa Kangaeru noda) NK 3027 P/2014 W4 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 47 observations 2014 Oct. 25 to 2015 Nov. 7. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.30 arc second. Recent observations show the residuals of -16" mainly for R. A. from an orbit in HICQ 2015. Epoch = 2016 Jan. 13.0 TT T = 2015 Dec. 29.66102 +/- 0.02197 (m.e.) TT Peri. = 67.43222 +/- 0.00293 Node = 33.35288 +/- 0.00012 (2000.0) Inc. = 15.27448 +/- 0.00008 q = 4.2610776 +/- 0.0000294 AU e = 0.3531010 +/- 0.0000173 a = 6.5869292 +/- 0.0000276 AU n' = 0.05830148 +/- 0.00000037 P = 16.905 +/- 0.0001061 years (+/- 0.04 day) The predicted orbit for the 2032 return is as follows: T = 2032 Nov. 25.82340 TT Epoch = 2032 Nov. 24.0 TT Peri. = 67.50213 e = 0.3544509 Node = 33.22720 (2000.0) a = 6.5963809 AU Inc. = 15.26890 n'= 0.05817622 q = 4.2582879 AU P = 16.942 years The following residuals in seconds of arc are from the above orbital elements: Date Code Residual(") Date Code Residual(") Date Code Residual(") 2014/ 141119 Q62 0.5- 0.3+ 150213 461 0.1+ 0.2+ 141025 F51 0.4- 0.0 141119 Q62 0.3- 0.1- 150213 461 0.2- 0.3+ 141025 F51 0.0 0.2- 141119 Q62 0.1- 0.4- 150213 461 0.2+ 0.3+ 141025 F51 0.2+ 0.2+ 141119 958 0.4- 0.5- 150214 G45 0.7- 0.1- 141118 F51 0.1- 0.0 141119 958 0.7- 0.7- 150214 G45 0.0 0.4+ 141118 F51 0.1+ 0.1- 141119 958 0.1- 0.6- 150214 G45 0.4+ 0.4+ 141118 F51 0.2+ 0.0 141120 W96 0.5- 0.7- 150214 G45 0.4- 0.1- 141118 F51 0.2+ 0.1- 141120 W96 0.5+ 0.1+ 150214 G45 0.8- 0.7- 141119 H01 0.1+ 0.3+ 141120 W96 0.4- 0.1+ 151106 461 0.1- 0.3- 141119 H01 0.0 0.3+ 141120 695 0.1- 0.6- 151106 461 0.1+ 0.2- 141119 H01 0.1+ 0.3+ 141120 695 0.1- 0.1+ 151106 461 0.4- 0.2- 141119 H01 0.1+ 0.2+ 141120 695 0.1+ 0.1- 151107 461 0.1+ 0.2+ 141119 695 0.7- 0.1- 141211 F51 0.1- 0.1+ 151107 461 0.1+ 0.0 141119 695 0.3+ 0.1+ 141211 F51 0.2+ 0.3+ 151107 461 0.1- 0.2- 141119 568 0.2+ 0.1+ 141211 F51 0.0 0.2+ 151107 461 0.2+ 0.0 141119 568 0.2+ 0.1+ 141211 F51 0.2- 0.1+ 141119 568 0.2+ 0.1+ 2015/ ( ) -------- Rejected Obs.
